the United States, residing at Dayton, win

the county of Montgomery and Statemof Ohio, have invented certain new and useful improvements in Door-Locks, of which the following is a specification.

This invention relates to builders hardware, and more especially to door securers; and the object of the same is to produce a portable lock lby means of which a door can be fastened or secured on the inside so that it will be impossible to open it from the outside.

rlhe object of the invention is to provide a portable device for the useof travelers, whereby doors with imperfect locks or with no locks `or keys can be fastened, or secured from the inside while the traveler is asleep.

lThe invention consists specifically in the construction hereinafter more rfully described and claimed, and shown in the draw ings, wherein Figure 1 is a horizontal section through the free edge of a door and its frame and the keeper therein, and a top plan view of the invention.

Fig. Q is a section on the line 2--2 of Fig. 1 and Fig. 3 a section on the line 3--3 of the saine view.

The door D closes against a shoulder S in the frame F as usual, and within the frame is the lock keeper K having an opening for the bolt, which latter' is not shown, as it is no-t necessary to the present invention. In fact, the frame may have the shoulder and keeper and there be no lock at all on the door, or an extremely imperf ect one, or the lock may not work or the key may be missing. So long as the frame has the keeper with its opening, our invention is applicable.

Coming now to the details of the inveni tion itself, the numeral 1 designates a stout and rather thin strip of metal perhaps six inches in length and an inch in width, having a hook 2 at its front end, a series of teeth 3 along its upper edge, and a transverse pin or stop 4L at its outer end. The strip is quite Ithin so that it may pass be tween the free edge of the door D and the frame F, and the hook 2 is of such size that it may pass through the opening O of the Application filed November 2631918. .1 Serial No. 264,200. i

kpen as!` illustrated in il" and, 2J-` Slidably mounted upon the strip: lis a lplate 5 having preferably near its outer edge a pair offeet .6,1 and threaded `through this `plateznear its inner edge is a set screw 7. The opening or slot 11 through the plate is so disposed that when the i strip is in proper position the feet rest against the frame F and the set screw against the door D. Secured to or formed on the outer face of the plate is a boss 9 having an upright slot 10 whose upper portion is alined with the top of the slot 11, and through these slots the strip passes as seen in Fig. Q. This block is shown as a separate element in the drawings, but it is quite possible to cast integral. The top of the opening in the boss and the opening in the plate are provided with teeth 13 of a size to receive the teeth 3 on the strip. An eccentric 1-1 has its head pivotally mounted at 15 within the slot 10 Iof the boss and its handle 16 radiating therefrom, the head of the eccentric underlying the lower edge of the strip 1.

In use, the hook :2 is engaged with the opening O in the keeper K, then the door is closed, then the plate 5 and boss 9 are slid up against the door and frame, the set screw striking the door and the feet 6 striking the frame as shown in Fig. 1, and the set screw may now be tightened to hold the parts in this position. The handle 16 of the eccentric is then moved downward so that the head 14 raises the strip 1 and moves its teeth 3 into engagement with the teeth 18, and thereafter it is impossible to` open the door from the outside or from the inside without first retracting the parts upon the strip so that the set screw no longer strikes the door. Thus is provided a portable door lock which may be used by the traveler in the manner hereinbefore set forth, and by the use of it he is safe from intrusion as suggested.

The foregoing description and the drawings have reference to what may be considered the preferred, or approved form of our invention. It is to be understood that we may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claim.

Having thus fully described our invention7 What We claim as new and desire` t0 secure by Letters Patent is In a door securer, the Ycombination with e strip toothed alongY its upper'edge and hooked at its front end; of a plate having an opening through which said strip passes,

a pair of feet projecting forward fronithe plate at one side of the opening, a set screw through the plate at the-'other side of its opening; a boss carried by the rear side of said plate and having an upright slot @lined with the opening therein, the
